Patented Nov. 22, 1932 UNITED STATES PATENT OFFICE ARTHUR KILLING, OF DORTMUND-HORDE, GERMANY, ASSIGNOB TO VEBEINIGIE STAHLWERKE .AKTIENGESELLSCHAET, OF DUSSELDORF, GERMANY VESSEL FOB HOLDING A LIQUID FOR HUMIDIFYING THE AIR Application filed December 1, 1930, Serial No.

This invention relates to an air humidifier. The known humidifiers for humidifying the air of living rooms, traffic Vehicles, such as railway cars or omnibuses, or the like, consist of a porous earthenware vessel filled with for humidifying the air of a given room, can

only be ascertained by experiment in each case. Another drawback is the earthenware vessels are very fragile.

In order to obviate these disadvantages, the object of the invention is to provide an air humidifier which employs, as the evaporative area, the surface of kieselguhr plates, produced by baking at a temperature of at least 1100 (1., the material being previously mixed, if desired with substances (cork, sawdust or the like) adapted to burn away in the kiln. Plates cut from these so-called sterchamol light blocks manufactured according to the above mentioned process have proved specially suitable. It has been found that the porosity, and therefore the evaporative action, of such plates is so great that it is suificient todip only a short piece of the plates in the liquid which is to be evaporated, the entire plate then becoming quickly and intensively saturated, and further that the'plates need only be placed in contact, end to end, without any other connection, for the adsorption to continue without any diminution.

A particularly favourable arrangement is to design the container for the liquid in such a way that, whilst its capacity is as large as possible, the contained liquid is shut off from the environment. a This prevents the liquid from being spilled out of the humidifier by the joltings to which the vessel may 499,350, and in Germany December 27, 1929.

be exposed when in use in spaces, 'such as on vehicles, which are not stationary. Such a method of sealing the vessel may consist in inwardly bending the upper rim of samethe side walls of which are preferably convex-so that the liquid is shut off from the environment when the frames carrying the absorbent plates are inserted in position.

The invention also comprises the feature of shaping the inwardly bent rim of the container in such a wayfor example, by suitably bending same upwards or round that the outer casing vof the air humidifier can be firmly attached thereto.

In order more clearly to understand the nature of the invention, reference is made to the accompanying drawings which illustrate diagrammatically and by way of exam ple two embodiments of the invention, and in which Fig. 1 is a side elevation, in partial section along the line I-I of Fig. 2;

Fig. 2 represents a plan of one embodiment of the new humidifier;

Fig. 3 is a longitudinal section, and

Fig. 4 a cross section, of a second embodiment. v

In the embodiment according to Figs. 1 and 2, 1 are the plates which absorb and give oil the liquid to be evaporated, said plates being disposed with theirlower portion dipping into the tray containing said liquid 2, the tray 3 being provided with a spout 4,through which it is filled with the liquid. The plates 1 are preferably assembled to a unit by means of a frame 5 or the like, in order to provide the plates with a hold and accelerate their insertion and removal. In order to protect the plates and a manner that the li uid 2 is sealed on the frame 5 being inserted in position. In order to increase the capacity of the vessel, the

side walls 9, in this embodiment, are made convex. The rim 7 of the vessel is curled outwards, so that the casing 6 of the humidifier can fit tightly on the rim7.

What I claim and desire to secure by Letters Patent of the United States is:

10 An absorption block in a-humidifier consisting of kieselguhr having a structure with pores formed by the burning out of combustibl e material mixedtherein.

In testimony whereof I afix my signa--' :5 ture.
